[Pdns-users] 4.2 to 4.3 Authoritative Upgrade path

[Giovanni Vecchi]

Hi guys,

my scenario is the following:
- several 4.2 Authoritative servers
- multi-master database configuration (Percona XtraDB Cluster for instance)

In order to upgrade to 4.3 and avoid downtime, is it safe to upgrade the
database schema first and every server then?

Thanks a lot
